摘要:二氯代化合物的用途十分广泛,故其合成的方法也一直备受关注,但在较成熟的方法中,虽然合成方法较多但都存在一定缺陷——反应过慢亦或是所用试剂毒性较强对环境危害性较大。现今,保护环境、倡导绿色化学俨然成为我们所共同努力的目标,如何减少使用毒性较强试剂和减少有毒有害气体的排放成为了我们对产品合成的一个共同努力方向。新型低共熔物条件下的反应不会导致反应过于激烈并能做到绿色化学。毕业论文利用了新型低共熔物介质,使用季铵盐类催化剂来快速高效的合成二氯代化合物,通过调整各种反应物的比例,希望得到简单高效的二氯代化合物快速合成法。关键词:低共熔物;绿色化学;三氯异氰脲酸;四丁基氯化铵;季铵盐。8750
New rapid two chlorinated compounds of the eutectic synthetic method research
Abstract: Due to the chlorinated compounds application is very extensively, much attention has been paid to the synthesis methods. But in the mature methods, there have many defects. For instance, synthetic reaction speed too slow or strong toxicity of reagents used more destructive to the environment. Nowadays, except environmental protection and advocate green chemistry has become our common efforts to target, how to reduce use of strong toxicity of reagents and poisonous and harmful gas emissions became our efforts. Reaction with the new eutectic material conditions will not be too intense and be clean. The paper that through using quaternary ammonium salt type catalysts and DES to synthetic the two chlorinated reaction rapidly and efficiently. By adjusting proportion of reactants, hoping for a simple and efficient rapid synthesis of chlorinated compounds.
Key words: DES; Green chemistry; TCCA ; TBAC ; Quaternary ammonium salt
